88RF PICCs can be configured to operate in the majority of applications developed for 88SC PICCs. Customers
migrating from 88SC devices to 88RF devices may be required to change their application software if they are using
functions identified in this appendix.
Error Handling
When a command packet containing errors is received by an 88SC or 88RF PICC, the status code returned in the
NACK response is the first error detected by the logic. The status code returned by 88RF PICCs may be different from
the status code returned by 88SC PICCs.
The Access Register (AR) and Device Configuration Register (DCR) definitions for 88RF PICCs are not exactly the
same as the 88SC PICC definitions. Some RFU bits have been assigned new functionality. The changes which impact
backward compatibility are summarized here.
88RF PICCs allows the Program Only Mode in User Zone 1 only. Program Only Mode is not allowed in User Zones 0,
2, or 3. The Access Register PGO bit is RFU for registers AR0, AR2, and AR3.
88RF PICCs do not support Write Lock Mode. The Access Register WLM bit is RFU.
88RF PICCs do not support Unlimited Checksum Reads. The Device Configuration Register UCR bit is RFU.
The CryptoRF Device Configuration Register ETA bit is RFU. The 88RF PICC attempts limit is always 15; it is no
longer configurable. [88SC PICCs allowed 4 or 8 attempts.]
88RF PICCs do not support Dual Access Mode. The CryptoRF Access Register bits which selected Dual Access Mode
have been assigned to another communication security mode.
Attempt Counters
Both the Password Attempts Counters (PACs) and Authentication Attempts Counters (AACs) have been redesigned to
allow 15 failed attempts before the Password or Key is locked. The coding of the PAC and AAC registers has been
changed to support the increased attempts counts.
Checksums
The requirement to supply a valid checksum when performing a write in Encryption Communication mode and
Authentication Communication mode is strictly enforced by 88RF PICCs. [88SC PICCs require a valid checksum if the
Access Register security mode bits for the current User Zone require that Encryption Communication mode or
Authentication Communication mode be active to write the User Zone. If Authentication or Encryption is not required,
then 88SC PICCs do not always require that a valid checksum be supplied to perform a write.]
